Abstract

Wireless power transfer (WPT) is an emerging technology that could lead to the breakthrough of plug-in Electric Vehicles (EVs). It enables transfer of electric power from one coil to the other based on the principle of electromagnetic induction. Inductive coupling (IC) and magnetic resonance coupling (MRC) are the two main methods of WPT. In this paper, MRC technique is used to effectively transfer power over large air gaps. Low power transfer efficiency (PTE) is the major challenge in WPT charged EVs. This may causes due to misalignment between the transmitter (Tx) and the receiver (Rx) coils. Lateral and angular are two commonly occurring misalignments in the practical scenario of WPTS. This paper presents the simulation analysis of various factors, which effects PTE. In the analysis, the lateral misalignments are performed for distinct airgaps between Tx and Rx. Various modes of angular misalignments are presented for a fixed value of airgap between coils. In addition, the paper provides the effect of various cores and aluminum shielding on PTE for distinct air gaps are documented.

横向和角度不对准对电动汽车无线充电系统能量传输效率的影响

无线电力传输(WPT)是一项新兴技术，可能会导致插电式电动汽车(ev)的突破。它可以根据电磁感应原理将电力从一个线圈传输到另一个线圈。电感耦合(IC)和磁共振耦合(MRC)是WPT的两种主要方法。在本文中，MRC技术被用来有效地转移功率在大的气隙。低功率传输效率(PTE)是WPT充电电动汽车面临的主要挑战。这可能是由于发射器(Tx)和接收器(Rx)线圈之间的不对准造成的。在WPTS的实际情况中，侧位和角位是两种常见的错位。本文对影响PTE的各种因素进行了仿真分析，在分析中，对Tx和Rx之间的不同气隙进行了横向错位。在线圈间气隙固定的情况下，给出了不同的角度失调模式。此外，本文还提供了各种芯和铝屏蔽对不同气隙的PTE的影响。
